Completionator is currently in OPEN BETA, which means there's a chance you'll run across some bugs or clunky interfaces. The biggest hurdle you may run into is that currently there isn't a way for users to add new games to the system. This is something that we'll be looking into for the future, but for now, you'll need to let us know if we're missing some of your games. Once you've registered and logged in, you can let us know in the Site Feedback forum. Thanks for your patience and understanding!
